2 Claims. (01. 199-55) My invention relates to improvements inmoldfastened stud 16 on which is mounted the mold cap filler bars forintertype line casting machines disc 11 for revolution.

As stated, the Similarcharacters refer to similar parts in the scale to which Figs. 5 and 6are drawn is larger several views. than that of Figs. 1 and 2. This lineof type con- With more particular reference to the desigsists of slug 27on which is small type 29, and the 55. nated parts: On the frame 12 ofthe machine is overhang 28 on which is larger type 1128. The 1.

relative position of the bar 25 to the type bar when the latter was inthe mold is indicated in dotted outline in Figs. 5 and 6.

In Figs. 9 and 10 are shown two views of a line of type assumed to havebeen cast in the mold 34 when the bar 25 was not used as a part thereof.This line of type consists of the slug 30 on which is small type 1231,and the slug overhang 31 on which is larger type (131. The height ofoverhang 31 is the greatest which can be cast in the mold 34 withoutextending the walls thereof by using the bar 25. It is easily seen thatletters 1131 are smaller than are letters a28 although both are drawn tothe same scale. This difference in height of the letters favorable tothose on the overhang 28 is attributable to the use of the mold fillerbar 25 as explained above.

In Figs. 7 and 8 are shown two views of a line of type which is largerthan any that could be cast in mold 34 without using the bar 25, yet itis no larger than is the type a28 on overhang 28 which, as stated, couldbe cast in the said mold by using bar 25 as a part thereof.

It is now clear that the use of the mold-cap filler bar 25 as an addedpart to the mold 34 makes possible the extended use of this mold beyondwhat could be cast therein, and that without using a different mold captherewith. It is also clear that the bar 25 may be used for increasingthe size of the mold and yet a slug with small letters cast thereon aswell as the overhang with larger letters thereon be cast in the saidextended mold.

That is, the use of the disclosed mold-cap filler bar increases therange of the type which may be machine.

The disclosed method of employing the moldcap, filler bar has, inpractice, been found tobe convenient. However, any other means offastening the same in place of the same general character also is withinthe purview of this invention, and I desire to have it so understood.

Having thus disclosed my invention, what I claim as new therein anddesire to secure by Letters Patent is,-

1. In mechanism of the kind described, a mold body, a mold cap adaptedfor being releasably fastened to the said mold body, the first elevatorjaws, a matrix, having a type recess therein, retained in the said firstelevator jaws operatively bearing on the said mold body disposing thesaid type recess adjacent the said mold cap and extended beyond thesame, a mold-cap filler bar having its bottom and rear edge operativelydisposed to rest on the said mold cap and on the said matrix adjacentthe said extended portion of the matrix recess with its front face flushwith the front face of the mold, lugs on the said filler bar, andfastening bolts and nuts bearing on the said lugs disposed to clamp thesaid mold cap filler bar and mold cap in operative position.

2.
